Which Firepower To Replace Your ASA 5500-X?
KB ID 0001705 Problem Well (at time of writing) only the ASA5516-X remains on sale (officially.) You may be able to get stock of the remainder of the ASA5500-X series as people clear their shelves, or they may be available as ‘refurb’ stock but they are disappearing. So you would think that the replacements would be better documented? Well it’s sketchy at best, and when you look a the data sheets for the new FPR...
AnyConnect: ‘Quick and Dirty’ Duo 2FA
KB ID 0001701 Problem Normally if I were deploying Duo 2FA with AnyConnect I’d deploy a Cisco RADIUS VPN on my LAN, (usually on my Duo Authentication Proxy). See the following article; AnyConnect: Enable Duo 2Factor Authentication However, last time I set this up, a colleague said ‘Oh by the way, you don’t need to do that, you can just point the firewall directly at Duo’. I was initially skeptical but I tried...
AnyConnect: Unauthorized Connection Mechanism
KB ID 0001699 Problem I was assisting a colleague to setup some AnyConnect for a client this afternoon, when all of a sudden I was met with this; VPN Logon denied, unauthorised connection mechanism, contact your administrator Solution This was a confusing one, I replicated the problem on my own test firewall. All I had done was change the AAA method from LOCAL to LDAP? It took me a while to figure out what was going on? The reason why...
AnyConnect: Allow ‘Local’ LAN Access
KB ID 0001689 Problem Note: This WONT WORK if you ‘force-tunnel’ or ‘tunnel-all’ remote VPN traffic, (if you are unsure Google ‘what’s my ip’ > Take note of it > Connect to AnyConnect and repeat the procedure, if your public IP address has changed to the IP address of the ASA then you force-tunnel/tunnel-all traffic). With more people remote working now, I’m getting a lot more...
Cisco FTD (and ASA) Creating AnyConnect Profiles
KB ID 0001685 Problem A few days ago I did an article on Deploying Cisco AnyConnect with the Cisco FTD, there I glossed over the AnyConnect profile section. For a long time now, we have been able to edit the AnyConnect profile from within the firewall (if we are running ASA code!) But for the FTD we need to take a step backwards and go back to using the ‘offline’ AnyConnect profile editor. Solution Firstly you need to...
Cisco ASA VPN Static to Dynamic IP (DHCP)
KB ID 0001683 Problem I had a call with a client last week, they are in one of my employer’s DCs, and their servers are behind a vASA. They had purchased some Meraki MX devices for their IT team who were working remotely (during the Covid-19 lockdown), and were struggling. Normally we would just suggest AnyConnect, but these guys were building new machines for their clients, and needed access directly to the domain from their...
